We investigated the effects of an ethanol extract of potato peel on T helper cytokines production in cultured murine Peyer’s patch cells ex vivo. Oral administration of the 70% ethanol extract at 100 mg/kg/day significantly enhanced the production of the Th1 cytokine IL-2 in response to concanavalin A. A decrease in the production of the Th2 cytokine IL-4 and the Th17 cytokine IL-17 was observed. The production of the Treg cytokine IL-10 was not affected. These results suggest that the potato peel extract stimulates Th1 immune response.

Saffron (Crocus sativus L.) is classified as a beneficial herb in the treatment of “Oketsu,” eliminating blood stagnation. The clinical symptoms of “Oketsu” include feeling cold and arthralgia. The pathological condition of “Oketsu” is considered to be increased blood viscosity and microvascular disorders.However, no useful biomarker has been reported for evaluation of the degree of “Oketsu.” Here, we investigated the clinical effect of saffron on the symptoms of “Oketsu” in patients with autoimmune diseases. At the same time, we measured the plasma levels of platelet factor 4 (PF-4) and beta-thromboglobulin (β-TG) as platelet activation markers. Seventy-one patients (66 women and 5 men, mean age 52.3 ± 16.1) were studied. They were administered saffron (300mg∼900mg) with traditional Kampo medicine. The clinical symptoms of “Oketsu” improved (80.9%, n=38/47) and we measured PF-4 and β-TG in pre-and post-saffron treatment periods. The plasma levels of PF-4 and β-TG significantly decreased after saffron therapy (PF-4 : before 49.6 ± 29.8, after 24.0 ± 19.6ng/ml, β-TG : before 117.5 ± 64.0, after 64.6 ± 47.1ng/ml;paired t-test, p < 0.0001, respectively). These results suggest that saffron is effective in treatment of the symptoms of “Oketsu” in allergy and collagen disease patients. Moreover, PF-4 and β-TG may be useful biomarkers of the degree of “Oketsu.”

[Objectives] Psychological factors are mentioned as one of the causes of menstrual pain and menstruation-associated symptoms. In this study, the relationship between menstrual pain, menstruation-associated symptoms, and personality was examined. [Methods] We targeted women who were menstruating and had provided informed consent. A questionnaire was conducted to obtain information on age, height, weight, degree of menstrual pain, menstruation-associated symptoms, and new personality inventory. Correlation analysis of Spearman was conducted on the relationship between menstrual pain, menstruation-associated symptoms, and personality.[Results] We distributed questionnaires to 250 persons and obtained responses from 166 persons. "Anxiety" correlated with menstrual pain and multiple factors of menstruation-associated symptoms, "depression" correlated with multiple factors of menstruation-associated symptoms. In addition, "aggression," "inferiority complex," and "non-cooperativeness" correlated with negative emotional factors of menstruation-associated symptoms.[Discussion] For "anxiety" and "depression," it was speculated that the symptoms became stronger due to poor circulation and serotonin deficiency during menstruation. In addition, the depressive aspects of "aggression," "non-cooperativeness," and "inferiority complex" were also considered to have an influence on negative emotional factors of menstruation-associated symptoms.[Conclusions] "Anxiety" correlated with menstrual pain and multiple factors of menstruation-associated symptoms, and "depression" correlated with multiple factors of menstruation-associated symptoms.

An 80-year-old woman presented with neck pain and paraparesis of Frankel C in her upper and lower extremities after falling. Imaging revealed an ankylosing cervical spine and a fracture line running obliquely from the anterior C3-4 to the posterior C4-5 level. Posterior fixation from the occi pit to T3 was performed using the RRS Loop Spine System and concomitant polyethylene tape fixation. This system is characterized by the uniqueness of how it screws to the occi pit and its use of a fixation rod with a larger diameter than in other instrumentation devices for use in the cervical region. Sublaminar banding using polyethylene tape was used to secure fixation. Her postoperative course was unremarkable, and her neck pain was relieved, although neurological improvement was minor. To our knowledge, this is the first report of an application of the RRS Loop Spine System to an ankylosing spondylitis patient with a cervical fracture.

BACKGROUNDAs an important determinant of patient satisfaction, waiting time, has gained increasing attention in the field of health care services. The present study aimed to illustrate the distribution characteristics of waiting time in a community hospital and explore the impact of potential measures to reduce outpatient waiting time based on a computer simulation approach.
METHODSDuring a one-month study period in 2006, a cross-sectional study was conducted in a community hospital located in Shanghai, China. Baseline data of outpatient waiting time were calculated according to the records of registration time and payment time. A simulation technique was adopted to investigate the impact of perspective reform methods on reducing waiting time.
RESULTSData from a total of 10,092 patients and 26,816 medical consultations were collected in the study and 19,947 medical consultations were included. The average of the total visit time for outpatients in this hospital was 43.6 minutes in the morning, 19.1 minutes in the afternoon, and 34.3 minutes for the whole day studied period. The simulation results suggested that waiting time for outpatients could be greatly reduced through the introduction of appointment system and flexible demand-orientated doctor scheduling according to the numbers of patients waiting at different time of the workday.
CONCLUSIONAdoption of an appointment system and flexible management of doctor scheduling may be effective way to achieve decreased waiting time.

Endoscopic ultrasound (EUS)-guided transgastric drainage has been performed as a less invasive procedure for pancreatic fistulas and intra-abdominal abscesses occurring after surgery in recent years. However, there are no reports of EUS-guided transgastric drainage of intra-abdominal abscesses following gastrectomy. This case report describes 2 patients who developed an intra-abdominal abscess following gastrectomy and underwent EUS-guided transgastric drainage. Both patients underwent laparoscopy-assisted distal gastrectomy with Billroth-I reconstruction for gastric cancer. The intra-abdominal abscesses were caused by postoperative pancreatic fistula that developed following gastrectomy. One patient underwent naso-cystic drainage and the other underwent only a needle puncture of the abscess cavity. EUS-guided drainage was performed safely and effectively, although 1 patient developed gastroduodenal anastomotic leakage related to this procedure. In summary, EUS-guided transgastric drainage is safe and technically feasible even in post-gastrectomy patients. However, it is necessary to be careful if this procedure is performed in the early period following gastrectomy.

Methods:
This study included 46 patients who underwent spinal reconstruction surgery for thoracolumbar osteoporotic vertebral fractures and kyphosis and were followed up for 1 year postoperatively. DJK was defined as an advanced kyphosis angle >10° between the LIV and one lower vertebra. The patients were divided into groups with and without DJK. The risk factors of the two groups, such as patient background, surgery-related factors, radiographic parameters, and clinical outcomes, were analyzed.
Results:
The DJK and non-DJK groups included 14 and 32 patients, respectively, without significant differences in patient background. Those with instability in the distal adjacent LIV disc had a significantly higher risk of DJK occurrence (28.6% vs. 3.2%, p=0.027). DJK occurrence significantly increased in those with the sagittal stable vertebra not included in the fixation range (57.1% vs. 18.8%, p=0.020). Other preoperative radiographic parameters were not significantly different. Instability in the distal adjacent LIV disc (adjusted odds ratio, 14.50; p=0.029) and the exclusion of the sagittal stable vertebra from the fixation range (adjusted odds ratio, 5.29; p=0.020) were significant risk factors for DJK occurrence.
Conclusions
Regarding spinal reconstruction surgery in patients with osteoporotic vertebral fractures, instability in the distal adjacent LIV disc and the exclusion of the sagittal stable vertebra from the fixation range were risk factors for DJK occurrence in the short term.

Background:
and Purpose To assess the long-term outcomes of intracranial dural arteriovenous fistula (DAVF) treated with stereotactic radiosurgery (SRS) alone or embolization and SRS (Emb-SRS) and to develop a grading system for predicting DAVF obliteration.
Methods:
This multi-institutional retrospective study included 200 patients with DAVF treated with SRS or Emb-SRS. We investigated the long-term obliteration rate and obliteration-associated factors. We developed a new grading system to estimate the obliteration rate. Additionally, we compared the outcomes of SRS and Emb-SRS by using propensity score matching.
Results:
The 3- and 4-year obliteration rates were 66.3% and 78.8%, respectively. The post-SRS hemorrhage rate was 2%. In the matched cohort, the SRS and Emb-SRS groups did not differ in the rates of obliteration (P=0.54) or post-SRS hemorrhage (P=0.50). In multivariable analysis, DAVF location and cortical venous reflux (CVR) were independently associated with obliteration. The new grading system assigned 2, 1, and 0 points to DAVFs in the anterior skull base or middle fossa, DAVFs with CVR or DAVFs in the superior sagittal sinus or tentorium, and DAVFs without these factors, respectively. Using the total points, patients were stratified into the highest (0 points), intermediate (1 point), or lowest (≥2 points) obliteration rate groups that exhibited 4-year obliteration rates of 94.4%, 71.3%, and 60.4%, respectively (P<0.01).
Conclusions
SRS-based therapy achieved DAVF obliteration in more than three-quarters of the patients at 4 years of age. Our grading system can stratify the obliteration rate and may guide physicians in treatment selection.

We report a case of a 72-year-old woman with a tumor arising from a colostomy site that had been created 25 years earlier when rectal amputation was performed for perforated sigmoid cancer. She was referred to our hospital due to complaints of pain from the colostomy. The diagnosis was carcinoma arising at the colostomy site with lymph node metastasis. Laparoscopic surgery was performed by attaching an Applied Alexis® wound retractor to the incision site of the colostomy. Lymph node dissection was performed and the left hemicolon was resected. Carcinoma arising from a colostomy site is rare. Laparoscopic surgery was considered to be a useful procedure because it allows for lymph node dissection and intestinal mobilization with minimal invasiveness.

BACKGROUND:
Pyrethroid (PYR) insecticides are widely used for controlling various pests. There are two types that differ in terms of usage: agricultural-purpose PYR (agriculture-PYR) and hygiene purpose PYR (hygiene-PYRs). Few studies exist on the exposure to these chemicals in small children. In this study, we conducted biomonitoring of urinary pyrethroid metabolites in 1.5-year-old children throughout the year.
METHODS:
Study subjects were 1075 children participating in an Aichi regional sub-cohort of the Japan Environment and Children's Study as of 18-month health check-up. The concentrations of four specific hygiene-PYR metabolites including 2,3,5,6-tetrafluoro-1,4-benzenedimethanol (HOCH2-FB-Al), and five common metabolites of hygiene- and agriculture-PYRs including 3-phenoxybenzoic acid (3PBA) and cis- and trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid (DCCA), were measured in urine samples extracted from soiled diapers using a triple quadrupole gas chromatograph-mass spectrometer.
RESULTS:
The highest detection frequencies were for 3PBA, followed by DCCA, 1R-trans-chrysanthemum dicarboxylic acid, and HOCH2-FB-Al. Among the six metabolites, urinary concentrations were seasonally varied. However, this variation was not observed in the most studied PYR metabolite, 3PBA. Spearman's correlation analysis demonstrated a significant positive correlation between FB-Al and DCCA (r = 0.56) and HOCH2-FB-Al and 4-methoxymethyl-2,3,5,6-tetrafluorobenzyl alcohol (r = 0.60).
CONCLUSIONS
This biomonitoring survey found widespread and seasonally specific exposure to multiple hygiene- and agriculture-PYRs in 1.5-year-old Japanese children.
